摘要

We present a lamp-pumped high-efficiency continuous-wave (cw) TEMoo mode Nd: YAG laser operated at the1318.8nm single line in the absence of intracavity etalons and additional apertures. A 15 W laser with beamquality M2 ＜ 2 has been achieved, which is, to our knowledge, the highest power in the cw TEMoo mode at1318.8nm within China. From the experimental results of laser behaviour at lines 1318.8nm and 1338.2nm, weconclude that the emission cross section of the transition line at 1318.8nm is larger than that at 1338.8nm.
